Comments on N=2 Born-Infeld Attractors

TL;DR

This paper discusses the N=2 Born-Infeld action with two vector supermultiplets, highlighting its relation to previous constructions and suggesting that new features may emerge for cases with more than two supermultiplets.

Contribution

It clarifies the relationship between the N=2 Born-Infeld action with two supermultiplets and earlier models, indicating potential for novel features in higher cases.

Findings

The N=2 Born-Infeld action with two supermultiplets is a complexification of earlier models.

Novel features are expected for cases with more than two supermultiplets.

The paper provides a comparative analysis of different N=2 Born-Infeld constructions.

Abstract

We demonstrated that the new N=2 Born-Infeld action with two N=1 vector supermultiplets, i.e. n=2 case considered as the example in the recent paper by S. Ferrara, M. Porrati and A. Sagnotti, is some sort of complexification of J. Bagger and A. Galperin construction of N=2 Born-Infeld action. Thus, novel features could be expected only for n>2 cases, if the standard action is considered.
